Wow, I didn't think they actually ever sold a set of those wings! They were advertised in the Hobie Hotline for 2 or 3 months back in the 80s, for just under $1,000 a set. They looked real neat to me, but the price was just way too prohibitive. I'm sure they're long out of production, but if you like, I'll check in my old Hotline "archives" and try to find the ad.
